Market Basket President and CEO Arthur T. Demoulas, along with the company's vice president and director of operations, was fired Monday after years of infighting. A key sticking point was apparently a decision Demoulas supported to institute an across-the-board 4 percent price cut.

Last year, Demoulas' cousin and rival gained control of the board and won a court judgment to distribute $300 million to shareholders, a move Demoulas opposed.
